scaffold were designed and synthesized. Among these, the most potent compound 7-((4, 6-diphenylpyrimidin-2-yl)amino)-N-hydroxyheptanamide (11a) inhibited HDAC6 with IC50 of 3.8 nM and showed 26~fold selectivity over HDAC1, better than those of ACY-1215. In cellular assay, these diphenylpyrimidines exhibited promising antiproliferative activities against different tumor cell lines. Altogether, this work
组蛋白脱乙酰酶6(HDAC6)在癌症治疗中发挥着重要作用,选择性HDAC6抑制剂(sHDAC6is)的开发近年来受到越来越多的关注。本研究设计并合成了一系列基于二苯基嘧啶支架的ACY-1215类似物。其中,最有效的化合物 7-((4, 6-二苯基嘧啶-2-基)氨基)-N-羟基庚酰胺 ( 11a ) 抑制 HDAC6,IC 503.8 nM,选择性比 HDAC1 高 26 倍,优于 ACY-1215。在细胞测定中,这些二苯基嘧啶对不同的肿瘤细胞系表现出有希望的抗增殖活性。总而言之,这项工作强调了二苯基嘧啶启发的 sHDAC6 抑制剂的治疗潜力,并为新型抗肿瘤药物的发现提供了有价值的先导化合物。
